The global (land and ocean) average temperature increase between 1850 and 2010 was 0.81 0 C using combined UK Met Office Hadley centre and University of East Anglia - Climate Research Unit HadCRUT3 dataset compared to the 1850 - 1899 period average temperature and 0.89 0 C using Goddard Institute for Space Studies - GISS dataset compared to the 1880 - 1899 period average temperature. All used temperature records show the 2000s decade (2001 - 2010) was the warmest decade. For the HadCRUT3 and GISS datasets the rate of the global average has increased from around 0.06 0 C per decade over last 100 years, to 0.18 - 0.22 0 C in last decade.
The best estimates for projected global warming in this century are a further rise in the global average temperature from 1.8 to 4.0 0 C for different scenarios that assume no further/additional action to limit emissions. The EU global temperature target is projected to be exceeded between 2040 and 2060, taking into account all six IPCC scenarios.
Europe
Europe has warmed more than the global average. The average temperature for the European land area for the last decade (2001 - 2010) was 1.2 °C above the 1850 - 1899 average, and for the combined land and ocean area 1.0 °C above. Considering the land area, 8 out of the last 13 years were among the warmest years since 1850. High-temperature extremes like hot days, tropical nights, and heat waves have become more frequent, while low - temperature extremes (e.g. cold spells, frost days) have become less frequent in Europe. The average length of summer heat waves over Western Europe doubled over the period 1850 to 2010 and the frequency of hot days almost tripled. The annual average temperature in Europe is projected to rise in this century with the largest warming over eastern and northern Europe in winter, and over Southern Europe in summer. High temperature events across Europe including temperature extremes such as heat waves are projected to become more frequent, intense and longer this century, whereas winter temperature variability and the number of cold and frost extremes are projected to decrease further. According to the projections, the most affected European regions are going to be the Iberian and the Apennine Peninsula and south - eastern Europe.

Global The global (land and ocean) average temperature increase between 1850 and 2009 was 0.74 0 C using combined Hadley centre and CRU datasets compared to the 1850 - 1899 period average temperature and 0.84 0 C using GISS dataset compared to the 1880 - 1899 period average temperature. All used temperature records show the 2000s decade (2000 - 2009) was the warmest decade. The rate of global average temperature change has increased from around 0.06 0 C per decade over last 100 years, to 0.16 - 0.20 0 C in last decade. The best estimates for projected global warming in this century are a further rise in the global average temperature from 1.8 to 4.0 0 C for different scenarios that assume no further/additional action to limit emissions. The EU global temperature target is projected to be exceeded between 2040 and 2060, taking into account all six IPCC scenarios. Europe Europe has warmed more than the global average. The annual average temperature for the European land area up to 2009 was 1.3 0 C above 1850 - 1899 average temperature, and for the combined land and ocean area 1 0 C above. Considering the land area, nine out of the last 12 years were among the warmest years since 1850. High-temperature extremes like hot days, tropical nights, and heat waves have become more frequent, while low - temperature extremes (e.g. cold spells, frost days) have become less frequent in Europe. The average length of summer heat waves over Western Europe doubled over the period 1850 to 2009 and the frequency of hot days almost tripled. The annual average temperature in Europe is projected to rise in this century with the largest warming over eastern and northern Europe in winter, and over Southern Europe in summer. High temperature events across Europe including temperature extremes such as heat waves are projected to become more frequent, intense and longer this century, whereas winter temperature variability and the number of cold and frost extremes are projected to decrease further. According to the projections, the most affected European regions are going to be the Iberian and the Apennine Peninsula and south - eastern Europe.

According to first estimates by EEA for the year 2010, EU-27 greenhouse gas emissions increased by 2.4 % compared to 2009 (with a margin of error of +/- 0.3 %). This was due to the return to economic growth in many countries and a colder winter leading to an increased heating demand. However, the increase in emissions was contained by a move from coal to natural gas and the sustained strong growth in renewable energy generation. EU‑27 emissions were 15.5 % below the 1990 level. This 2010 increase follows a 7 % drop in 2009 (compared to 2008), largely due to the economic recession and the growth of renewable energy generation. Between 1990 and 2010, greenhouse gas emissions in the EU-27 decreased in all main emitting sectors except in the transport sector, where they increased considerably. In the EU-15, CO 2 emissions from public electricity and heat production also increased.
In the EU-15, estimated 2010 GHG emissions increased by 2.3 % (+/– 0.7) compared to 2009. This implies that EU‑15 greenhouse gas emissions were approximately 10.6 % below the 1990 level in 2010 (1) or 10.7 % below the base-year level. The European Union remains well on track to achieve its Kyoto Protocol target (an 8% reduction of its greenhouse gas emissions compared to base-year level, to be achieved during the period from 2008 to 2012). 2010 emissions of all EU-12 Member States that have a Kyoto target were well below their Kyoto target, except in Slovenia.
A detailed assessment of progress towards Kyoto targets and 2020 targets in Europe is provided in EEA's 2011 report on Greenhouse gas emission trends and projections .

In blue, the source of the original anomalies is the combined UK Met Office Hadley Centre and Climate Research Unit dataset, HadCRUT3. The global mean annual temperature deviations are in relation to the base period 1961-1990. In red, the source of the original anomalies is NASA's GISS dataset. The anomalies are in the source in relation to the base period 1951-1980. The global mean annual temperature deviations have been adjusted to be relative to the period 1850-1899 (HadCRUT3) and 1880 - 1899 (NASA's GISS). All original data is rounded to the nearest 2 decimal places. The trend lines show the 10-year centred moving average of the original anomalies for both datasets relative to the period 1880-1899. The dotted lines show the annual anomalies of the HadCRUT3 (blue) data set and GISS (red) respectively.

How to read the map:
Warm days are defined as being above the 90th percentile of the daily maximum temperature.
Grid boxes outlined in solid black contain at least 3 stations and so are likely to be more representative of the grid-box. Higher confidence in the long-term trend is shown by a black dot. Area averaged annual time series of percentage changes and trend lines are shown below each map for one area in northern Europe (Green line, 5.6 to 16.9 E and 56.2 to 66.2 N) and one in south-western Europe (Pink line, 350.6 to 1.9 E and 36.2 to 43.7 N).
